TURBINE WATER-WHEEL.

SPECIFICATION forming part of Letters Patent No. 238,644, dated March 8, 1881.

Application filed July 11, 1879. I

To all whom it may concern:

Be it known that I, REVILO J. BRISAOK, of Ashlaud, in the county of Greene and State of New York, have invented a new and Improved Turbine YVater-Wheel, of which the following is a specification.

The object of this invention is to increase the power and efficiency of turbine wheels by increasing the number of buckets without obstructing the discharge of water from the wheel.

It consists in providing the wheelwith a novel construction and arrangement of buckets, whereby double the number of buckets are applied to the wheel, thereby increasing its power without interfering in the slightest with the inlet and discharge of water from the buckets.

1n the accompanying drawings, Figure l is a sectional side elevation of my improved wheel, the section being taken on line as m, Fig. 2; and Fig.2 is a horizontal section of the wheel on line 3 y of Fig. 1.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A A are the up per and lower rings of the wheel, provided with spider B B, through which the central shaft 0 is run.

D represents the long buckets, having concave faces a, reaching from the outer periphery of the wheel inward to a convex extension, I), that reaches in to the inner circlelof the rings in a direction opposite to that in which the wheel turns. These buckets are so placed as to leave a space between the inner ends of the extensions, forming discharge-ports 0 toward the center of the wheel for each bucket.

E represents the short buckets, reaching from the outer periphery of the wheel, and

- having concave faces (I and short extensions 0, terminating short of the narrowest space between the ends of the extensions b and the next adjoining long bucket, whereby the full force of the water acts on the shorter buckets without their reducing the capacity of the discharge-ports. The buckets being arranged at equal distances apart, with their outer faces, h, convex or curved, as shown, all the inlet as well as the outlet openings have the same capacity, while the curved or convex faces h permit the water to freely flow therein.

This wheel is placed within a scroll-case arranged so as to give a narrower channel for the passage of water as its volume increases.

The advantages of the wheel thus constructed are numerous and apparent to those acquainted with their construction and operation. It has great power, owing to the number of buckets, but at the same time frees itself quickly of the water, and thus there is no drawback in consequence of dead water remaining in the wheel.

I am aware that a water-wheel having alternating sets of long and short buckets with concave faces is old, and such I do not wish to be understood as claiming, broadly, as of my invention.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- A water-wheel having alternating sets of long and short buckets D E, arranged at equal distances apart, and extending from the outer periphery of the wheel inward, as shown and described, and having inner concave faces, a d, and outer convex faces, h, substantially as and for the purpose specified.
